Abstract:
Objective To evaluate the clinical efficacy and safety of recipient-site pre-expansion via tumescent anesthesia in facial fat grafting .Methods Facial fat grafting was operated through the technology of recipient-site pre-expansion via tumescent anesthesia .The high-frequency ultrasonography was used to record the changes of soft tissue thickness , blood flow signal and transplant area in certain-points.Theresult were analyzed by SPSS 11.5.The survival rates of fat grafting were compared by Kruskal-Wallis H test.The area of soft tissue blood flow signals were analyzed by variance analysis .The patients' postoperative satisfaction rates and pain were evaluated by mean value .Results 14 cases were treated , with obvious improvement .Results of high frequency ultrasonography showed the median and quartile spacing of the soft tissue thickness was 70.1％(53.85％), 56.4％(51.95％), and 16.7％in the first month, third month and the sixth month after operation , separately.The difference between the three groups was statistically significant (H=1.4 ×108, P<0.05).The area of soft tissue blood flow signals was(3.97 ±0.84)‰,(2.21 ±0.55)‰,(6.89 ±2.39)‰,(14.61 ±4.66)‰,(9.39 ±3.94)‰, (15.87 ±3.02)‰before the operation, 24 hours, the first month, third month and the sixth month after operation,separately.The difference between the six groups were statistically significant (F=3.471, P <0.05).No complication occurred in the following-up period.Patients were satisfied with the pain relief. Conclusions It is safe and effective to apply recipient-site pre-expansion via tumescent anesthesia in fat grafting.
